简单的PHP cURL文件上传到Azure存储blob

Question

我遇到了使用cURL创建新的/简单的PHP脚本/函数的问题，以便使用共享密钥身份验证将简单文件(image.jpg)从本地服务器上传到Azure存储-blob容器。我不想(出于其他原因)使用SDK和/或多个文件/库。我只需要一个功能-文件上传-就是它。

文档没有提供带有文件覆盖的上传(POST)的完整示例。https://learn.microsoft.com/en-us/rest/api/storageservices/fileservices/authentication-for-the-azure-storage-services

还不清楚什么是必需的标头，以及签名/身份验证属性需要什么标头。(例如，具有不同标题的多个MSDN站点-https://learn.microsoft.com/en-us/rest/api/storageservices/fileservices/put-blob

有人想分享一下这个简单的例子吗？

<?php
error_reporting(E_ALL);
ini_set('display_errors', 'On');
date_default_timezone_set('UTC');
$destinationURL = 'https://mystorage.blob.core.windows.net/blob1/image.jpg';
$accesskey = "qJXTMmw2Esal8/tXgfWk0RLwMNJ6OQKEt0E8EMZ8VhQrzGi5uqJqeKvi1l7iqnOddp7bdtai5rPpC6ynHttl1w==";
$storageAccount = 'mystorage';
$filetoUpload = realpath('./image.jpg');
function upload($filetoUpload, $storageAccount,$destinationURL,$accesskey) {
$currentDate = date("D, d M Y H:i:s");
$postFields = array(
'extra_info' => '123456',
'file_contents'=>'@'.$filetoUpload
);
$headerText=""
."x-ms-version: 2015-02-21n"  
."x-ms-date:" .$currentDate." GMTn"
."Content-Type: text/plain; charset=UTF-8n"  
."x-ms-blob-content-disposition: attachment; filename=".$filetoUpload."n"  
."x-ms-blob-type: BlockBlobn"  
."x-ms-meta-m1: v1n"  
."x-ms-meta-m2: v2n"  
;
$hash = hash_hmac('sha256', $headerText, base64_decode($accesskey), true);
$sig = base64_encode($hash);
$headerText.="Authorization: SharedKey ".$storageAccount.":".$sig."n";
$headerText.="Content-Length: 280";
$headers = explode("n", $headerText);
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_URL, $destinationURL);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
echo ('Result<br/>');
print_r($result);
echo ('Error<br/>');
print_r(curl_error($ch));
curl_close ($ch);
return;
}
upload($filetoUpload, $storageAccount,$destinationURL,$accesskey);

您可以尝试以下代码片段。
